A metal 'M' reacts with N2 to give a compound 'A' (M3N). 'A' on heating at high temperature gives back 'M' and 'A' on reacting with H2O give a gas B. 'B' turns CuSO4 solution blue on passing through it. M and B can be
Al and NH3
Li and NH3
Na and NH3
Mg and NH3
CH3CH2CH(OH)CH3 and CH3(CH2)2CH2OH can be distinguished by
Lucas test
Iodoform test
Victor-Meyer's test
All of the above

Racemic compound has
equimolar mixture of enantiomers
1 : 1 mixture of enantiomer and diastereomer
1 : 1 mixture of diastereomers
1 : 2 mixture of enantiomers
A.
equimolar mixture of enantiomers
When 50% d-form is mixed with 50% l form, a racemic mixture is obtained. Hence, an equimolar mixture of the enantiomers (dextro or laevo forms) is called racemic mixture. It is represented as dl form or ± form and is optically inactive due to external compensation. Separation of racemic mixture into d- and l-forms is called resolution.
In which of the following ways does the hydride ion tend to function ?
An electrophile
A nucleophile
A free radical
An acid
