What would an 8 carbon alkane be called?
Longer chains are named as follows: pentane (five-carbon chain), hexane (6), heptane (7), octane (8), nonane (9), and decane (10). These prefixes can be seen in the names of the alkanes described in Table 1.
What is the name for an 8 carbon chain?
Explanation: An eight-carbon continuous-chain alkane has the formula C8H18 . Its IUPAC name is octane (oct- meaning eight, -ane meaning single bonds).

Which of the following could be a cyclic alkane?
question. (B) C3H6 – is the correct option. The monocyclic saturated hydrocarbons known as cycloalkanes (sometimes known as naphthenes, although distinct from naphthalene) are monocyclic saturated hydrocarbons in organic chemistry.
What are the first eight members of the alkane series also give its molecular formula and condensed structural formula?

| Name | Molecular formula of alkane | Condensed structural formula of alkane |
|---|---|---|
| methane | CH4 | CH4 |
| ethane | C2H6 | CH3CH3 |
| propane | C3H8 | CH3CH2CH3 |
| butane | C4H10 | CH3(CH2)2CH3 |
What is the name of this alkane C7H16?
Heptane or n-heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16, and is one of the main components of gasoline (petrol).
How do you name cyclic compounds?
A cyclic (ring) hydrocarbon is designated by the prefix cyclo- which appears directly in front of the base name. In summary, the name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain).
What is the structure of Methene?
Methene word is made up of: ‘meth’ + ‘ ene’. ‘Meth’ means the presence of only one carbon atom. The suffix ‘ ene’ refers to the presence of a double bond between 2 carbon atoms. -We all know that for the presence of a double bond a major requirement is that there should be at least 2 carbon atoms.
Does Methyne exist?
We know that an organic compound must contain at least two carbon atoms to form double and triple bonds. Here, there is only one carbon atom and thus we can conclude that methene and methyne does not exist. Note: Alkanes are saturated hydrocarbons with single bonds between carbon atoms.
How many hydrogen atoms are in a cyclic alkane containing six carbon atoms?
Cycloalkanes are ring or cyclic structures containing carbon-carbon single bonds. They have the general formula CnH2n and the simplest of these cyclic hydrocarbons has the formula C3H6. Each carbon atom has two hydrogen atoms attached (Figure 1.6.
How many chain isomers are there for an alkane that contains 7 carbon atoms?
9
Straight-Chain and Branched Alkanes

How many forms of branched alkane can be produced with a six carbon alkane?
For higher alkane homologs (n > 4), more than two isomers are possible. For example, pentane has three possible isomers in which one is a linear straight-chain alkane and two are branched alkanes….Branched Alkanes.
| CH3- | methyl |
|---|---|
| CH3CH2CH2CH2- | butyl |
| CH3CH2CH2CH2CH2- | pentyl |
What are cyclic alkanes?
Cycloalkanes, as their name tells us, contain rings. Some cyclic compounds have atoms that are shared between two or more rings. These are spirocyclic, bridged-ring, and fused-ring compounds. The general formula for an alkane is CnH2n+2.
How do you name cyclic alkanes?
