Compound A formed in the following reaction reacts with B to give the product C. Find out A and B. CH3-C CH + Na A B CH3- (C)C C-CH2- CH3 |CH2 + NaBr

1. A = CH3-C -C Na+, B = CH3-CH2-CH2-Br
2. A = CH3-CH=CH2, B = CH3-CH2-CH2-Br
3. A = CH3-C -C Na+, B = CH3-CH2-CH3
4. A = CH3-CH2-CH3, B = CH3-C CH

The incorrect statement regarding conformations of ethane is :

1. The dihedral angle in staggered conformation is 60 .
2. Ethane has infinite number of conformations.
3. Eclipsed conformation is the most stable conformation.
4. The conformations of ethane are inter-convertible to one-another.
