Which of the following statements are incorrect

Options

A. EtOH is more acidic than water.
B. Both `C-O` bonds in `Me-underset(O)underset(||)(C)-OH` are of equal length due to resonance.
C. `Ph-NH_(2)` is more basic then `Me-NH_(2)`
D. `-underset(..)overset(..)(O)-overset( :O: )overset(||)(C)-R` is a positive mesomeric effect `(+M)` showing group.

Answer

A, B, C

Explanation

(i). Water is more acidic than Et-OH
(ii). Bond length is not equal since R.S. are not equivalent
(iii). `Ph-overset(..)(N)H_(2)` is weaker base than `Me-NH_(2)`, due to involvement of lone pair of electron in resonance.
(iv). If key atom is lone pair bearing it will show `+M` effect
