Haloalkanes & Branched Alkanes [Part 1] | Name → Structure

The video tutorial explains how to draw organic molecules by converting their names into structural formulas. It covers three examples: 2,3,4-trimethylhexane, 2-chloro-3-ethyloctane, and 4-bromo-2,3-diethyl-5-methyldecane. The process involves identifying the parent chain, adding functional groups, and ensuring the correct number of hydrogens. The tutorial emphasizes the importance of understanding the naming conventions and structural rules, such as the CNH 2N+2 rule for alkanes, and highlights exceptions for haloalkanes.

What is the first step in drawing the structure of 234 trimethyl hexane?

• Identify the functional groups

• Draw the parent chain

• Add hydrogens to the structure

• Calculate the number of carbons

How many hydrogens should a carbon atom have in a simple alkane?

• Two

• Five

• Three

• Four

In 2-chloro, 3-ethyl octane, what is the position of the chloro group?

• Position 3

• Position 4

• Position 2

• Position 1

Why does the CNH2N+2 formula not work for haloalkanes?

• Because it only applies to alkenes

• Because it only applies to branched alkanes

• Because halogens replace hydrogens

• Because it only applies to cyclic alkanes

What is the parent chain in 4-bromo, 2-3 diethyl, 5-methyl decane?

• Hexane

• Octane

• Decane

• Pentane

How many ethyl groups are present in 4-bromo, 2-3 diethyl, 5-methyl decane?

• Three

• Two

• One

• Four

What analogy is used to describe the process of converting a chemical name to a structure?

• Building a model

• Writing a story

• Following a recipe

• Solving a puzzle
