Answer 1

CH3 SH+ HIS 10) HzC# CSS-C- CH CH3 -H20 CH3 Thiols on oxidation reaction give corresponding oxidized product having S-S bond as shown above. 03 H1N 2 4 5-ethyl-6-methylheptanal Since the longest carbon chain has 7 carbon atoms, rootword is 'hept' suffix for aldehyde is 'al' In prefix naming, alphabet 'e' gets priority (ethyl) than 'm' (methyl) Hence 5-ethyl and 6-methyl

The IUPAC name of the any compound contains 3 parts prefix+ rootword + suffix Prefix = any substitutents rootword = longest chain containing most number of carbons if the chain contains 1 carbon = meth 2 carbon = eth 3 carbon = prop 7 carbon = hept 4 carbon = but 8 carbon = oct 5 carbon = pent 9 carbon = non 6 carbon = hex and so on Suffix = if the compound contains single bond (C-C) only then suffix 'ane double bonds (C=C) 'ene triple bonds 'yne For selecting prefix numbering, the substituents numbers has to be given in such way that the sum of the all substituents should be as less as possible. For selecting rootword chain, the chain with more number of carbons has to be selected In all the given compounds alkanes are present, hence the suffix is 'ane' in all the four compound For all the compounds, blue coloured part of the name is prefix. red coloured part of the name is rootword and pink coloured part of the name is suffix
