Vedclass · Answer

(C) $1$. Alkynes have a linear geometry around the triple bond,so they cannot show geometrical isomerism. This statement is correct.$2$. Propane $(CH_3-CH_2-CH_3)$ can show conformational isomerism due to rotation around the $C-C$ single bonds. This statement is correct.$3$. Chain isomerism is only possible for alkanes with $4$ or more carbon atoms (e.g.,$n$-butane and isobutane). Methane,ethane,and propane do not show chain isomerism. Therefore,the statement that 'all alkanes show chain isomerism' is incorrect.$4$. Meso-tartaric acid has a plane of symmetry,making it optically inactive due to internal compensation. This statement is correct.
