Select incorrect statement (s).

Answer»

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

Solution :
(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
