Select incorrect statement (s).

Options

A. Conjugate acid of pyrrole is anti-aromatic
B. `Me_(3)C-underset(O)underset(||)C-ND_(2)` can't tautomerise
C. `CH_(3)-S^(ϴ)` is less stable then `CH_(3)O^(ϴ)`
D. Optically pure `underset(Me)underset(|)EtCH-underset(H)underset(|)overset(Me)overset(|)C-CH=O` racemize
during tautomerisation

Answer

a,b,c,d

Explanation

(b) `Me_(3)C-underset(O)underset(||)C-ND_(2)iffMe_(3)C-overset(O)overset(|)C=ND`
( c) `CH_(3)S^(-)` is more stable than `CH_(3)-O^(-)` due to larger size of sulphur atom
