"The negative part of the addendum adds on to the carbon atom linked with the least number of hydrogen atoms." This statement is called:

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 $C$.

In the given reaction sequence,identify the final product $C$:
$CH_2=CH-CH=CH_2$ $\xrightarrow{HCl, 40^{\circ}C} A$ $\xrightarrow{HI} C$
(Note: The reaction proceeds via electrophilic addition to a conjugated diene.)

Ozonolysis of the given compound yields:

Hydrolysis of ozonide of $but-1-ene$ gives

$Isobutylene$ $\xrightarrow[(2) H_2O]{(1) O_3}$ $Product$
