This video talks about the effect of substrate on the rate of an SN1 reaction. It helps compare various substrates having the same type of leaving group and also briefly helps recall the mechanism of the SN1 rate.

00:00- Recall the mechanism of SN1 reaction.
00:50- Factors affecting the rate of an SN1 reaction.
01:16- Why does the strength of a nucleophile not affect the rate of an SN1 reaction?
01:50- Comparing various substrates for their reactivity towards an SN1 reaction.
6:15- What happens in the next video?

This video talks about the mechanism involved in an SN1 reaction. It also elaborates on what is a rate determining step and how it affects the rate of a reaction. We learn how to calculate the rate of an SN1 reaction and also, what is the order of an SN1 reaction. In the end, it tells why the nucleophile does not affect the rate of an SN1 reaction while the concentration and type of substrate does.

00:00- Introduction
00:30- What is nucleophilic substitution?
1:15- How does nucleophilic substitution occur?
1:40- Mechanism of SN1 reaction
3:00- What is RDS?
