Q. Which of the following statements (s) is (are) not true?
A) Carbanions and carbonium ions, usually exist in ion pairs or else solvated
B) Acidity increases and basicity decreases in going from left to right across a row of Periodic Table
$CH_{4} < NH_{3} < H_{2}O < HF(acidity)$
$CH_{3}^{-} > NH_{2}^{-} > OH^{-} > F^{-}(basicity)$
C) $RCOOH$ like $R$COR reacts with $H_{2}NOH$ to give an oxime
D) Decreasing order of ionizing power of solvents is
$CF_{3}COOH > HCOOH > H_{2}O > CH_{3}COOH > CH_{3}OH > C_{2}H_{5}OH > \left( CH_{3} \right)_{2}SO > CH_{3}CN$
Explanation
(c)
Aldehydes and ketones combine with a variety of compounds of the $Z - NH_{2}$ to form oxime
