Four reports are produced for hydrocarbon samples in a fuel study.
A report is accepted only if the molecular formula is that of an alkane and the stated number of covalent bonds formed by each carbon atom is correct.
| Report | Molecular formula | Covalent bonds formed by each carbon atom |
|---|---|---|
| J | C9H18\text{C}_9\text{H}_{18}C9H18 | 4 |
| K | C9H20\text{C}_9\text{H}_{20}C9H20 | 3 |
| L | C10H20\text{C}_{10}\text{H}_{20}C10H20 | 3 |
| M | C10H22\text{C}_{10}\text{H}_{22}C10H22 | 4 |
Which statement is correct?
Report K should be accepted.
Report L should be accepted.
Report M should be accepted.
Report J should be accepted.
