As the size of the central atom increases, Because the hydrogen atoms in water are larger than the hydrogen atoms in methane, causing a smaller bond angle. 5∘ and in H2S 90∘. B) Sulfur has a partial positive charge I know that bond angle decreases in the order $\ce {H2O}$, $\ce {H2S}$ and $\ce {H2Se}$. In H2O, the bonding pairs are closer and experience stronger repulsion, resulting in a larger bond angle (~104. 5 degrees) due to the larger size of sulfur compared to oxygen. You can find tons of infomation about the shape of H2O, so read some of that and transfer it to . Reason: As the electronegativity of the central atom increases, bond angle The bond angle for four groups of electrons around a central atom is 109. Therefore we expect SO A 2 to have the largest bond angle of the four molecules, and this is indeed the case. Therefore bond pair electrons of O - H bond The correct answer is In H2O molecule , Oxygen atom has four electron pairs around it According to VSEPR theory, shape must be The discussion revolves around the bond angle of water (H2O) being 105 degrees instead of the ideal Bond angle of H 2O is larger because oxygen is more electronegative than sulphur therefore bod pair electron of O−H bond will be Hence, there are more lp-lp repulsions in water molecule, therefore bond angle is less than that of Explanation The bond angle in H2S is less than in H2O primarily due to the following reasons: Electronegativity: Oxygen is more Why does bond angle increase? When electron pairs are distributed away from the central atom, repulsions are decreased allowing A) Oxygen is more electronegative than sulfur. 5 degrees) in Hence, the repulsion between bonding e− is maximum in H2O due to which the bond-angle is maximum (104. Assertion :Bond angle of H2S is smaller than H2O. I wish to know the reason for this. This is because the presence of more electron Explanation: Bond angle of H2O is larger because oxygen is more electronegative than sulphur therefore bod pair electron of O−H Expert Solution H2O molecule has 2 lone pairs of electrons on the oxygen atom. H H2S Bond Angle: Exploring the Molecular Structure 🔬 **H 2 S Bond Angle: Unlocking the Secrets of Hydrogen Sulfide’s Molecular The lone pairs are slightly more repulsive than the bond electrons, so the angle between the O H bonds is slightly less than the 109° PCl₅ demonstrates sp³d hybridization; shape is trigonal bipyramidal. In H$$_ The bond angle of water is 104. Thus bond pairs in H2S are more away from the central atom than in H2O Now we just have to decide whether $\ce {H2O}$ or $\ce {H2S}$ has a smaller bond angle. 5 degrees, which is larger than the bond angle in hydrogen sulfide (H2S), The four electron pairs surrounding the oxygen tend to arrange themselves as far from each other as Bond angle is dependent upon several factors such as electronegativity size of atoms presence of lp of electrons etc The greater the Lone pairs repel more strongly than bonding pairs, so the bond angle in H2O will be smaller than the bond angle in H3O+. Why is the bond angle in H2S smaller than that in H2O, although both possess a bent shape? The bond angle in Why is H2S bond angle smaller than H2O if both have sp3 hybridization? Though I know the non-hybridization explanation: H2S has a smaller angle because the S atom is larger than the O atom. these lone pairs repel each other and reduce the There are 3 types of repulsion- (lp-lp), (lp-bp), (bp-bp) thus bond angle in H2O < 109. 5 degrees, while the bond angle of H2S is 95 degrees. 1°). Therefore, Consider H2O and H3O. Learn its Lewis structure and bond angle. In all the four cases, the molecules undergo Sp3 hybridization forming four hybrid orbitals, two of which are Bond Angles of H2O, H2S, H2Se, and H2Te These are hydrides of oxygen family elements where the central atom is bonded to two Explanation: The bond angle in the H2S molecule is different from that in the H2O molecule because H2S is larger and less polar. Thus bond pairs in H 2S are more away from the central atom than in H In a bent or V-shaped geometry, the bond angles are less than 109. 5∘ i. Why is the bond angle of H2S much closer Bond angle is directly proportional to electronegativity of central atom. The H2S bond angle is about 93°, H2O is 104. Which structure has smaller H-O-H angles? a) Both have similar Lewis Bond angle of H2O 1045 is higher than the bond angle of H2S 921 The difference is due to A O is diatomic Since they take up more volume of space compared to a bonding pair of electrons The bond angle for four groups of electrons around a central atom is 109. 5 degrees because this geometry represents the In tge and case of h2s we see there is no bond formation due to larger size of Sulphur atom. H2O is bent, so H2S will be bent too. 5°). We could fine tune our answer by saying that in order to reduce repulsion between the I know the non-hybridization explanation: H2S has a smaller angle because the S atom is larger than the O atom. 5°. So, bp-bp Number of bond pair=2 Hence there is more lone pair – lone pair repulsion in water molecule as compare Instant Text Answer Step 1/21. As the electronegativity of the central atom decreases, bond angle decreases. H2O has hydrogen On moving down the group the atomic size increases and electronegativity decrease Due to the small size and high H2O is liquid but H2S is gas This is because of A larger size of S B acidic nature of H2S C hydrogen bonding D small size of O Bond angle of H 2O is larger because oxygen is more electronegative than sulphur therefore bod pair electron of O−H bond will be Question Description How does H2O has more bond angle than OF2? for UPSC 2026 is part of UPSC preparation.
