\((2)\) Methoxy group is electron releasing.
Therefore increases stability by donating electron.
\((3)\) Chlorine is also electron withdrawing but its effect is less than \(-NO_2\) group.
Hence, correct order of stability.
\((4)\)
$ -\mathrm{OCH}_3,-\mathrm{NO}_2,-\mathrm{CN},-\mathrm{CH}_3-\mathrm{NHCOCH}_3,$ $ -\mathrm{COR},-\mathrm{OH},-\mathrm{COOH},-\mathrm{Cl}$
$(A)$ $AgCN / KCN$
$(B)$ $RCOOAg / RCOOK$
$(C)$ $AgNO _{2} / KNO _{2}$
$(D)$ $AgI / KI$
આમાંથી કયું બંધારણ વ્યવહારીક ફોર્માલ્ડિહાઈડ માટે માન્ય પ્રમાણભૂત બંધારણ નથી?
$(II)$ $CH_3COOH$
$(III)$ $ CH_3CH_2COOH $
$(IV)$ $C_6H_5COOH $
પદાર્થો માટે ઘટતી એસિડિકતાનો સાચો ક્રમ કયો છે ?
