1 2-butene
2 2-butyne
3 2-butanol
4 butanal
Explanation:
2-butene, $\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{3}$ will exhibit geometrical or cis-trans isomerism.

An optically inactive natural $\alpha$-amino acid is
1 Glycine
2 Alanine
3 Lysine
4 Valine
Explanation:
The structure of glycine is: The compounds which don't have a chiral center that is incapable of optical orations is said to be optically inactive . The amino acid has not stereocentre from which they do not rotate the plane polarized light so, this is optically inactive in nature.

Different conformations of the same molecule are called
1 Isomers
2 Epimers
3 Enantiomers
4 Rotamers
Explanation:
Conformational isomers are also known as rotamers and the isomerism as rotamerism. - Epimers are diastereomers that contain more than one chiral centre but differ from each other in the absolute configuration at only one chiral centre.
