Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students‟ responses to questions and that every associate understands and applies it in the same correct way. ...

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...

Discusses nomenclature, reactions and mechanisms of carboxylic acids and their derivatives. This includes nitriles, amides, acyl halides, esters and anhydrides. Goes over preparation and reaction of all derivatives, as well as their relative reactivity.

1. The correct name of the following molecule would be: A) 2-ethyl-3,3-dimethylheptane B) 6-ethyl-5,5-dimethylheptane C) 3,4,4-trimethyloctane D) 2-butyl-3-methylpentane E) 2-sec-butyl-2-methylhexane 2. What is the name given to the Newman projection of the butane conformation shown here? A) anti B) gauche C) staggered D) eclipsed E) skewed 3. At room temperature, the various conformations of butane A) do not interconvert with only the anti form present. B) do n...

This document contains in class notes on carboxylic acids and carboxylic acid derivatives from a college level organic chemistry class. These notes go in depth on how to name carboxylic acids and carboxylic acid derivatives, the order of reactivity of carboxylic acids and carboxylic acid derivatives, and numerous reactions of carboxylic acids and carboxylic acid derivatives (transesterification, Fischer's esterification, and hydrolysis to name a few).

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 thiscase, 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 / working and this is shown in the ‘Comments’column or by each stage o...

2 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 show correct bond angles. • Skeletal formulae must show carbon atoms by an angle or suitable inte...
