Class 12th

The electronic spectrum of [Ti(H?O)?]³? shows a single broad peak with a maximum at 20,300 cm?¹. The crystal field stabilization energy (CFSE) of the complex ion, in kJ mol?¹, is: (1 kJ mol?¹ = 83.7 cm?¹)

The mechanism of S?1 reaction is given as:

A student writes general characteristics based on the given mechanism as:
(a) The reaction is favoured by weak nucleophiles.
(b) R⊕ would be easily formed if the substituents are bulky.
(c) The reaction is accompanied by racemization.
(d) The reaction is favoured by non-polar solvents.
Which observations are correct?
