The C — O bond length (136 pm) in phenol is slightly less than that in methanol (142 pm).

(i), (ii) and (v)

(i), (ii) and (iii)

(i), (iii) and (iv)

(i) and (iv)

The C—O bond length (136pm) in phenol is slightly less than that in methanol (142pm).

The $C — O$ bond length ( $136 p m$ ) in phenol is slightly less than that in methanol ( $142 p m$ ).
