In this video, we look at Markownikoff’s rule for electrophilic addition to alkenes. First we explore why we make two products when we add a hydrogen halide to an asymmetric alkene, looking at the major product and minor product. We then explore how the stability of the carbocation intermediate determines the major and minor product. We look at primary, secondary and tertiary carbocations and what determines their stability.

This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.
