I have some questions about "and" & "comma+and". Can you help me clarify whether the following sentences are correct or not?

1. Jim washed the bedroom, and he cleaned the window

2. Jim washed the bedroom and he cleaned the window

3. Jim washed the bedroom, and cleaned the window

4. Jim washed the bedroom and cleaned the window

Which of the sentense is correct? Experts plz help

e-GMAT wrote:1. Jim washed the bedroom, and he cleaned the window - CORRECT - Two independent clauses are connected using , AND

2. Jim washed the bedroom and he cleaned the window - INCORRECT - Since these are two independent clauses, they should be connected using , AND

3. Jim washed the bedroom, and cleaned the window - INCORRECT - Since this is a list of only TWO verbs, it should be connected using AND

4. Jim washed the bedroom and cleaned the window - CORRECT - Two verbs are connected using AND

5. Jim washed the bedroom, wiped the furniture, and cleaned the window - CORRECT - More than TWO elements in a list are connected using ,AND


Your question relates very closely with the sentence structure - i.e. how are clauses connected. I just posted my response in the post below and you will benefit from it. Essentially in the Free Preview of e-gmat Sentence Correction course, we have added two new concepts that explain "Sentence Structures". Feel free to access those concepts to gain better insight into punctuation required for connecting clauses.
