Statement-1: is more stable
Statement-2: Torsional strain and flag pole interactions cause the boat conformation to have considerably higher energy than the chair conformation.

For cyclohexane, which of the following factors does not make the boat conformation less stable than the chair conformation

Statement-1 : B_(2)O_(3) is more acidic than BeO. Statement-2 : Ionisation energy of B is more than Be.

Statement-1: NH_(3) is more basic than NF_(3) Statement-2: F is more electronegative than H.

Statement-1: NH_(3) is more basic than NF_(3) Statement-2: F is more electronegative than H.

Statement-1 : Ce^(4+) is more stable than Ce^(3+) . Statement-2 : Ce^(4+) has noble gas configuration.

Stereoisomers, which can be interconverted simply by rotation about sigma bonds, are conformational isomers while those, which can be converted only by breaking and remaking of bonds and not simply by rotation, are called configurational isomers. The angle between C-C and C – H bonds on adjacent carbon atoms in any conformation is called dihedral angle. The cyclic compounds most commonly found in nature containing six membered rings can exist in a conformation that is almost completely free of strain. The most stable conformation of cyclohexane is chair form. According to Bayer strain theory, the greater deviation from the normal tetrahedral angle, greater is the angle strain or torsional strain and hence lesser is the stability of the cycloalkane. Dihedral angle in staggered (gauche) and eclipsed conformation are:
