  • question_answer 81)   In both water and dimethyl ether \[(C{{H}_{3}}-\underset{\centerdot \centerdot }{\overset{\centerdot \centerdot }{\mathop{O}}}\,-C{{H}_{3}})\]oxygen atom is central atom and has the same hybridisation, yet they have different bond angles. Which one has greater bond angle? Give reason.


      In dimethyl ether, the bond angle will have higher value. This will be due to more repulsion between bond pairs of\[C{{H}_{3}}\] group attached in ether than between bond pairs of hydrogen attached to oxygen in water.
