a) The information required to determine the molecular formula of W and suggest its structures is unreadable in the provided image. b) i) Suggest an identity for compound X. Step 1: Analyze the observations from the tests. • Test A (PCl₅): No white fumes. This indicates the absence of -OH groups (alcohols or carboxylic acids). • Test B (Bromine water): No reaction. This indicates the absence of C=C or C≡C double/triple bonds and phenols. • Test C (2,4-dinitrophenyl hydrazine): Orange precipitate. This indicates the presence of a carbonyl group (C=O), meaning X is either an aldehyde or a ketone. • Test D (Tollen's Reagent): No reaction. This indicates the absence of an aldehyde group. Step 2: Combine the inferences. From Test C, X is an aldehyde or a ketone. From Test D, X is not an aldehyde. Therefore, X must be a ketone. Step 3: Consider the given constraint. Compound X has "less than 4 carbon atoms". The smallest ketone possible has 3 carbon atoms. Step 4: Identify the compound. The only ketone with less than 4 carbon atoms is propanone. The identity of compound X is Propanone. c) Give the systematic name for each of the following compounds. i) CH_3CH(CH_3)CH_2NH_2 Step 1: Identify the longest carbon chain containing the amine group. This is a 3-carbon chain (propane). Step 2: Number the chain to give the amine group the lowest possible number. The amine group is on carbon 1. Step 3: Identify substituents. There is a methyl group on carbon 2. The systematic name is 2-methylpropan-1-amine. ii) CH_3CH_2COCl Step 1: Identify the functional group, which is an acyl chloride (-COCl). Step 2: Identify the longest carbon chain containing the acyl chloride group. This is a 3-carbon chain. Step 3: The parent carboxylic acid would be propanoic acid. For acyl chlorides, the suffix -oic acid is replaced by -oyl chloride. The systematic name is Propanoyl chloride. d) State the reagents and reaction conditions for the conversions in the table below. | Reaction | Reagent
