Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Alkane}\mathrm{with}\mathrm{two}\mathrm{carbon}\mathrm{atoms}\mathrm{is}\mathrm{ethane}. \\ \mathrm{General}\mathrm{formula}\mathrm{of}\mathrm{alkane}={\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}(\mathrm{In}\mathrm{this}\mathrm{case},\mathrm{n}=2) \\ \mathrm{Molecular}\mathrm{formula}\mathrm{of}\mathrm{ethane}\mathrm{is}{\mathrm{C}}_2{\mathrm{H}}_{2\times 2+2}={\mathrm{C}}_2{\mathrm{H}}_6 \\ \mathrm{Structural}\mathrm{formula}\mathrm{of}\mathrm{ethane}\mathrm{is}:{\mathrm{CH}}_3{\mathrm{CH}}_3 \end{gathered}$$
