Let's compare the words letter by letter according to alphabetical order:
All words start with "Ch". Let's look at the third letter:

Cha...

Cha...

Che...

Che...

Che...

Comparing words starting with "Cha" (1 and 2):

Character (2) comes before Charge (1) because 'a' comes before 'r' at the 5th position (Chara... vs Charg...).

Sequence so far: 2, 1

Comparing words starting with "Che" (3, 4, 5):

The 4th letters are: 'm' in Chemist, 'a' in Cheap, 'c' in Check.

Alphabetical order of 4th letters: 'a' (Cheap) < 'c' (Check) < 'm' (Chemist).

So the order is: 4, 5, 3

Combining both groups, the correct dictionary sequence is 21453.
