(3)
A
biodegradable
δ+ C or polar C=O group
can be attacked by nucleophiles
2
Q
Explain how 3 isomeric products are formed when when HY reacts with but-1-ene
A
major product exists as a major product
third isomer is 1-bromobutane
because it is obtained via primary carbocation

A
bromine water
pent-2-ene: colourless/ decolourises
cyclopentane: no reaction
