(methyl free radical) has planar structure with sp2 hybridisation of 'C' atom. The odd electron is present in unhybridised 2p orbital.
(methyl carbonium ion) has also trigonal planar structure (sp2).
(methyl carbanion) has tetrahedral structure (sp3) and one of the hybrid orbitals contains the lone pair of electrons.

When the temperature of reactions will increase then the effect on pH value will
increase
decrease
first increases then decreases
remains same.
