A-level CHEMISTRY 7405/2 Paper 2 Organic and Physical Chemistry 3.2 Marking procedure for calculations Full marks should be awarded for a correct numerical answer, without any working shown, unless the question states ‘Show your working’ or ‘justify your answer’. In this case, the mark scheme will clearly indicate what is required to gain full credit. If an answer to a calculation is incorrect and working is shown, process mark(s) can usually be gained by correct substitution / wor...

A-level CHEMISTRY 7405/1 Paper 1 Inorganic and Physical Chemistry Mark scheme June 2021. 3.12 Organic structures Where students are asked to draw organic structures, unless a specific type is required in the question and stated in the mark scheme, these may be given as displayed, structural or skeletal formulas or a combination of all three as long as the result is unambiguous. In general • Displayed formulae must show all of the bonds and all of the atoms in the molecule, but need not s...

1(a) The only correct answer is D (2-bromo-2-methylpropane) A is not correct because 1-bromobutane is a primary halogenoalkane so hydrolyses more slowly than the tertiary halogenoalkane B is not correct because 2-bromobutane is a secondary halogenoalkane so hydrolyses more slowly than the tertiary halogenoalkane C is not correct because 1-bromo-2-methylpropane is a primary halogenoalkane so hydrolyses more slowly than the tertiary halogenoalkane (1) Question Number Answer Mark 1(b) The...
