Ethylene reacts with sulphur monochloride to form

An alkene $'A'$ contains three $C-C$,eight $C-H$ $\sigma$ bonds and one $C-C$ $\pi$ bond. $'A'$ on ozonolysis gives two moles of an aldehyde of molar mass $44 \ u$. Write the $IUPAC$ name of $'A'$.

The major product in the following reaction is:

What is the major product formed during the debromination of $meso-2,3-dibromobutane$?

Ozonolysis of an alkene with molecular formula $C_9H_{18}$ yields $2, 2-$ dimethylpropanal and $2-$ butanone. The alkene is ....................
