$CH_3-CH_2-CH_2-CH_3 \xrightarrow[HBr]{AlCl_3}$ Product in the above reaction is:

Identify the total number of carbon atoms present in undecane.

The molecular mass of a hydrocarbon is $86 \ g/mol$. What is the number of its possible structural isomers?

Identify product $P$ in the following reaction: $C_2H_5MgBr + NH_3 \rightarrow P$

Isomers of hexane,based on their branching,can be divided into three distinct classes as shown in the figure. The correct order of their boiling point is

An alkane $(Y)$ requires $8$ moles of oxygen for complete combustion and on chlorination with $Cl_2/h\nu$, $(Y)$ gives only one monochlorinated product $(Z)$. The total number of primary carbon atoms in $(Y)$ is . . . . . . .
