Write the structural formula and IUPAC name of the following:
(i) A carboxylic acid with four C-atoms.
(ii) An alkyne with three C-atoms.
(iii) An alcohol having one C-atom.
Answers
Answer:
1) The IUPAC name is BUTANOIC ACID and the common name is butyric acid.Butanoic acid is a carboxylic acid with the structural formula CH3CH2CH2-COOH. where −COOH is the functional group.The structural formula is C4H8O22) Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings).
The answer is Propyne
(OR)
1-Butyne is a terminal alkyne, with the first three carbon atoms in the chain adopting a linear shape because of the triple bond. 2-Butyne is a structural isomer of 1-butyne, having a carbon-carbon triple bond in the middle of the chain.
3)A primary (1°) alcohol is one in which the carbon atom (in red) with the OH group is attached to one other carbon atom (in blue). Its general formula is RCH2OH..
(OR)
The answer is METHANOL
