Question

Convert the following condensed structures into skeletal structures:

a. CH₃CH₂CH₂CH₂CH₂CH₂OH

b. CH₃CH₂CH₂CH₂CH₂CH₃

c.CH₃CH₂CHCH₂CHCH₂CH₃CH₃CH₃

d. CH₃CH₂CH₂CH₂OCH₃

e. CH₃CH₂NHCH₂CH₂CH₃

f.CH₃CH₂NHCH₂CH₂CH₃

Short answer

Condensed structures display atoms but few, if any, bonds.

Step-by-step solution

Define condensed structure

Condensed structures display atoms but few, if any, bonds.

Define skeletal structure

Skeletal structures display bonds but few, if any, atoms.

Consider a succession of central atoms that are linked from left to right

In all the given questions, carbon is the central atom moving along the parent chain, which is the chain containing the greatest number of carbon atoms in succession.

Determine the anticipated bonds per atom

We know as per rules for Lewis structures:

1. Carboncan form 4 bonds as it has 4 valence electrons.
2. Oxygen has 2 lonepairsand 2 unpaired electrons, and so can form 2 bonds.
3. Hydrogen will form 1 bond as it has 1 valence electron.
4. Nitrogen will form 3 bonds as it has zero formal charge.

Check whether the octet rule is obeyed or not

According to the octet rule, atoms gain or lose electrons in order to achieve an outer shell electron configuration that is closest to that of a noble gas. The skeletal structures are made keeping this rule in mind.
