Question

What will be the bond angle C-0-H in alcohol if hybridisation of C and O atom possess sp${}^3$hybridisation?

• A. 111${}^{\circ }$42'
• B. 199${}^{\circ }$28;
• C. 108${}^{\circ }$30'
• D. 109${}^{\circ }$

Answer 1

Answer: (C)

The bond angle C-0-H in alcohol is slightly less than tetrahedral angle (109${}^{\circ }$28' ). This is due to larger repulsion between the lone pairs of oxygen. The bond angle C-0-H in alcohol is 108${}^{\circ }$30'
