Question

The $C-O-C$ bond angle in dimethyl ether is:

• A. ${111.7}^o$
• B. ${108.5}^o$
• C. ${109}^o$
• D. ${120}^o$

Answer 1

Answer: (A)

${111.7}^o$

The $C-O-C$ angle in ethers is greater than ${111.7}^0$. Because of the greater electronegativity of oxygen than carbon, the $C-O$ bonds are slightly polar and are inclined to each other at an angle of ${111.7}^0$
