Answer : The correct option is, (C) 2-octene
Explanation :
Structural formula or bond-line formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.
In bond-line formula, the lines are used between the bonded atoms and the atoms are also shown.
The basic rules for naming of organic compounds are :
First select the longest possible carbon chain.
For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
A suffix '-ane' is added at the end of the name of alkane.
If two of more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.
In the given hydrocarbon, the longest possible carbon chain number is 8 that means we add prefix 'oct' and suffix '-ene' for double bond. So, the name of given molecule will be, 2-octene.
Hence, the name of the given molecule is, 2-octene.
