(a)
Write the major product in the following reaction : $\displaystyle 1+1+1$
(b)
Define Chirality.
(c)
Why racemisation occurs in $\displaystyle \mathrm{S}_{\mathrm{N}} 1$ reaction ?
Marking-scheme solution
(a)
(b)
The objects / compounds which are non-superimposable on their mirror images
are said to be chiral and this property is known as chirality.
(c)
Because of formation of planar carbocation / sp2 hybridised carbon so
nucleophile can attack equally from both sides.
