The number of grams of bromine that will completely react with $5.0 \ g$ of pent$-1-$ene is $...... \times 10^{-2} \ g$. (Atomic mass of $Br = 80 \ g/mol$) [Nearest Integer]

The hydrocarbon with seven carbon atoms containing a neopentyl and a vinyl group is:

Which of the following aliphatic compounds will discharge the red colour of bromine?

An alkene $A$ (molecular formula $C_{5}H_{10}$) on ozonolysis gives a mixture of two compounds $B$ and $C$. Compound $B$ gives a positive Fehling's test and also forms iodoform on treatment with $I_{2}$ and $NaOH$. Compound $C$ does not give Fehling's test but forms iodoform. Identify the compounds $A, B$ and $C$. Write the reaction for ozonolysis and the formation of iodoform from $B$ and $C$.
