Dec 26, 2017 · Since compound A contains a total of 8 carbon atoms, each of B and C contain 4 carbon atoms. Again, on dehydration, alcohol C gives but-1-ene. Therefore, C is of straight chain and hence, it is butan-1-ol. On oxidation, Butan-1-ol gives butanoic acid. Hence, acid B is butanoic acid. Hence, the ester with molecular formula C 8 H 16 O 2 is ...
(b) But-1-ene and other products can be made by the dehydration of butan-2-ol. (ii) Explain why but-1-ene does not show geometrical isomerism. (iii) An alternative dehydration of butan-2-ol produces geometrical isomers.

The butan-1-ol on oxidation with chromic acid would give butan-1-oic acid. 4) On dehydration, butan-1-ol will lose water molecule to give but-1-ene. Therefore, the correct structure of the starting ester is CH 3 -CH 2 -CH 2 -CO-O-CH 2 -CH 2 -CH 2 -CH 3 .
To eliminate water from an Alcohol requires the removal of the -OH from one Carbon atom and the removal of an H atom from a neighbouring Carbon atom. There alcohols where this may not happen. Dimethylpropan-1-ol is an example where there are no Hydrogen atoms on Carbon 2 to remove.
peak 1 and peak 2 were obtained respectively. NMR spectra of both peaks 1 and 2 showed that it was still a mixture of isomers. Hence, compound in peak 1 was separated on AMYLOZE-2 column and gave two more sets i.e. compound in peak 1A and compound in peak 1B. However, compound in peak 2 could not be separated on the same column.

Propan-2-ol is not dissimilar to propan-1-ol in that it appears as a colourless liquid at room temperature. It can be physically distinguished from propan-1-ol by its comparatively pleasant odour and its bitter, instead of fruity taste. Chemically, propan-2-ol is a secondary alcohol and a structural isomer of propan-1-ol.
