https://pmt.physicsandmathstutor.com...n%201%20MS.pdf

can you explain the answer to these question as i dont get it

2a) why do the Br disappear and form a double bond
2b) never learnt resistant
3aii)how is it a isomer can you draw the 2 molecule so i can visualise it.
3bii)how does lowering temp increase yield
and 7bi) onwards is it year 2 content as i dont know how to answer it

Resistant means it can’t be oxidised i.e a tertiary alcohol

2a) you've read the question incorrectly. The alkene MAKES the bromo compound.
2b) "resistant to" means that no reaction happens
3a(ii) The double bond can form between the last two carbon atoms
3b(ii) Unclear from the information given. Maybe the reaction is an equilibrium in the forward exothermic direction.
7b(i) I don't know which board you are studying - you wold have to look at the spec.

3aii why does the 4th carbon have Ch3 whereas the last carbon on the original molecule have ch2.

2a is understand the double bond but why do br dissapear
