A Level Chemistry B H433 past paper update

We have corrected an error in one of the A Level Chemistry B H433 (Salters) question papers used in the November 2020 exam series.

The error appeared in the H433/01 Fundamentals of Chemistry question paper, which took place on Tuesday 6 October 2020 – Afternoon.

In Section A question 12, for answer option B, the word ‘substitution’ was used when it should have been the word ‘addition’.

Question 12, answer option B should read:

‘The electrophilic addition of chlorine with alkenes.’
