Solution :(A) ` = underset(CO_(2)C_(2)H_(5))underset(|)(CO_(2)C_(2)H_(5))`or `underset(CO_(2)C_(3)H_(7))underset(|)(CO_(2)CH_(3))`
(B) Mixture of `underset(CO_(2)Na^(+))underset(|)(CO_(2)^(-)Na^(+))` andeither `C_(2)H_(5)OH` or `CH_(3)OH` and `C_(3)H_(7)OH`
(D) `underset(CO_(2))underset(|)(CO_(2)^(-)) Ca^(+ +)""` (E) = `underset(CONH_(2))underset(|)(CONH_(2))`
`C_(3)H_(7)` is EITHER `CH_(3)CH_(2)CH_92) ` - or `(CH_(3))_(2)CH`.
If the iodoform test is positive A is .
