323192 If (dl) or ( \({\mathrm{\pm}}\) ) 2-methyl butanoic acid were esterified by reaction with (dl) or \({\mathrm{( \pm)}}\) 2-butanol, how many optically active compounds would be present in the final equilibrium reaction mixture?

323193 Assertion :
tert-Butoxide is a stronger base than \(\mathrm{OH}^{-}\)or \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{O}^{-}\)but is a much poorer nucleophile.
Reason :
A negatively charged ion is always a more powerful nucleophile than its conjugate acid.

323194 Assertion :
Acidic character of alcohols follows the order primary \(>\) secondary \(>\) tertiary.
Reason :
Acidic character of alcohols is due to the presence of polar \(-\mathrm{O}-\mathrm{H}\) group.

323195 Assertion :
Addition of \(\mathrm{CH}_{3} \mathrm{OH}\) to phenyl magnesium bromide gives benzene.
Reason :
\(\mathrm{CH}_{3} \mathrm{OH}\) is a stronger acid than benzene.
