(a)
Interpretation:
The expanded structural formula of a continuous-chain alkane with the formula
Concept Introduction:
The structural representation of organic compound can be done in 2D and 3D. In two-dimensional representation, there are four types of representation in which an organic compound can be drawn. They are,
- Expanded structural formula
- Condensed structural formula
- Skeletal structural formula
- Line-angle structural formula
Structural formula which shows all the atoms in a molecule along with all the bonds that is connecting the atoms present in the molecule is known as Expanded structural formula.
Structural formula in which grouping of atoms are done and in which the central atoms along with the other atoms are connected to them are treated as group is known as Condensed structural formula.
Structural formula that shows the bonding between carbon atoms alone in the molecule ignoring the hydrogen atoms being shown explicitly is known as Skeletal structural formula.
Structural formula where a line represent carbon‑carbon bond and the carbon atom is considered to be present in each point and the end of lines is known as Line-angle structural formula.
In condensed structural formula for

- Summarize the nomenclature rules for alkanes, alkenes, alkynes, and aromatic compounds. Correct the following false statements regarding nomenclature of hydrocarbons. a. The root name for a hydrocarbon is based on the shortest continuous chain of carbon atoms. b. The suffix used to name all hydrocarbons is -ane. c. Substituent groups are numbered so as to give the largest numbers possible. d. No number is required to indicate the positions of double or triple bonds in alkenes and alkynes. e. Substituent groups get the lowest number possible in alkenes and alkynes. f. The ortho- term in aromatic hydrocarbons indicates the presence of two substituent groups bonded to carbon- 1 and carbon-3 in benzene.arrow_forwardWhy are different conformations of an alkane not considered structural isomers?arrow_forward. With very reactive agents, such as the halogen elements, alkanes undergo reactions, whereby a new atom rep laces one or more hydrogen atoms of the alkane.arrow_forward
