Question

Identify $X, Y$and $Z$ from the information given below: $X = A$ chiral amino acid which loses its chirality on treatment with lithium aluminium hydride.
$Y =$ The decarboxylation product of $\alpha$-amino (secondary)acid, $C_{5}H_{9}O_{2}N.$
$Z = I$t is formed when $A (C_{3}H_{4}O_{3})$ is treated with (i) $NH_{3} (ii) NaBH_{4}$
[A forms oxime, gives iodoform test and liberate $CO_{2}$ with $NaHCO_{3}$].

	X	Y Z
1	Alanine	Serine
2	Serine	Alanine
3	Serine	Alanine
4	Aspartic acid	Serine
