#No, the range of the spells stays the same

The description of the War Caster feat (PHB, 170) says:

When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, instead of making an opportunity attack. The spell must have a casting time of only 1 action and must target only that creature.

The description of the Reach weapon property (PHB, 147) says:

This weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for opportunity attacks with it.

When the War Caster feat allows you to cast a spell instead of an opportunity attack, the range does not increase for your spells; you still cast a spell with a 5-foot or touch range, and creatures outside of that range can't be targeted by those spells.

Reach only increases the range at which you gain an opportunity attack. After that, you can choose to attack the creature with either your whip or a spell, but the creature is out of range for a touch or 5-foot range spell.

You could potentially use the sorcerer's Distant Spell metamagic option to increase the range of the spells cast, and then you could use them at that range.
