The correct statement regarding the comparison of staggered and eclipsed conformations of ethane is

The eclipsed conformation of ethane is more stable than staggered conformation because eclipsed conformation has no torsional strain

The eclipsed conformation of ethane is more stable than staggered conformation even though the eclipsed conformation has torsional strain

The staggered conformation of ethane is more stable than eclipsed conformation because staggered conformation has no torsional strain

The staggered conformation of ethane is less stable than eclipsed conformation, because staggered conformation has torsional strain.

Solution

The staggered conformation of ethane is more stable than eclipsed conformation because staggered conformation has no torsional strain

Due to the absence of torsional strain staggered conformation of ethane is more stable than eclipsed conformation of it.

Question

The IUPAC name of the compound $CH subscript 3 CH space equals space CHC space identical to space CH$ is

pent - 4 yn - 2- ene

pent - 3-en - 1-yne

pent - 2- en-4 -yne

pent - 1- yn-3- ene

Solution

pent - 3-en - 1-yne

CH subscript 3 space minus CH space equals CH space minus space straight C space identical to CH Pent space minus space 3 minus space en minus space 1 minus yne
