Answer
Koolwaterstowwe is verbindings wat bestaan uit koolstof (C) en waterstof (H) atome. Hulle is die hoofkomponente van organiese chemie en kan verskeie strukturele vorms aanneem, soos kettings of ringe.

Answer
Die struktuurformule van verbinding E, Butan-1-ol, kan as volg geteken word:
H H H HO
| | | |
H--C--C--C--C--H
