Question

Each packet should also contain 30 1-inch plastic connectors that represent a pair of electrons, either a lone pair or a bonding pair. The hydrocarbon compounds with the following molecular formulas are all classified as alkanes. CH_4, C_2 H_6, C_3 H_8, C_4 H_10, C_5 H_12, C_6 H_14, C_7 H_16 C_8 H_18, C_9 H_20, C_10 H_22 Your TA will assign you three of the alkanes above. Your assigned alkanes are; Draw the Lewis structure, write the condensed structural formulas and name for each of the alkanes assigned to you. Use the molecular model kit lo construct several examples of your alkane compounds.

Explanation / Answer

In a condensed structural formula, or semi-structural formula, covalent bonds are not always shown and atoms of the same type bonded to one another are grouped together.
