Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

Need help asap! Thanks

An allylic substrate is more favorable for unimolecular E1/Sn1 reactions than a 3° substrate because relative to the 3° carbocation the allylic carbocation is ----------- in energy
because it's ---------- by resonance.
O A. lower; destabilized
OB. lower; stabilized
OC. higher; destabilized
O D. higher; stabilized

If 2-iodobutane had been used to alkylate saccharin instead of iodoethane the reaction would have been
O A. slower; an achiral product
OB. faster; a racemic mixture
OC. slower; a racemic mixture
O D. faster; an achiral product
and would have produced
