Alkanes Worksheet and Key 1. Answer the following. a. What is the general formula for a noncyclic alkane? C?H? b. If a noncyclic alkane contains 15 carbon atoms, how many hydrogen atoms does it contain? 2. Draw the line bond structures of following types of hydrocarbons using four carbon atoms: a. two noncyclic alkanes b. two cycloalkanes 3.
These write-on worksheets will ask learners to use their knowledge of hydrocarbons in an applied context. Calculation questions are included to give opportunities to practise mathematical skills within this topic.
23 sty 2023 · The general formula for alkanes is C N H 2N +2; the simplest possible alkane is therefore methane, CH 4. The next simplest is ethane, C 2 H 6; the series continues indefinitely. Each carbon atom in an alkane has sp³ hybridization. Alkanes are also known as paraffins, or collectively as the paraffin series.
