Read the following statements carefully. False statement among these statements is

1..$\begin{array}{l}1 2 3 45\\ {\mathrm{CH}}_2=\mathrm{CH}-{\mathrm{CH}}_2-\mathrm{C}\equiv \mathrm{CH}....10\mathrm{\sigma },3\mathrm{\pi }\end{array}$

2.. $\begin{array}{l}{\mathrm{sp}}^2{\mathrm{sp}}^2 {\mathrm{sp}}^2{\mathrm{sp}}^2\\ {\mathrm{CH}}_2=\mathrm{CH}-\mathrm{CH}={\mathrm{CH}}_2\end{array}$

3..$$\begin{gathered} {\left({\mathrm{CH}}_3\right)}_3\stackrel{+}{\mathrm{C}} ....... 9 \mathrm{H}.\mathrm{C} \mathrm{hydrogens} \mathrm{and} \mathrm{thee} +\mathrm{I} \mathrm{groups}(\mathrm{methyl} \mathrm{gps}); \\ {\left({\mathrm{CH}}_3\right)}_2\stackrel{+}{\mathrm{C}}\mathrm{H}...... 6 \mathrm{H}.\mathrm{C} \mathrm{hydroges} \mathrm{and} \mathrm{two} +\mathrm{I} \mathrm{groups}(\mathrm{methyl} \mathrm{gps}); \end{gathered}$$
