How do we do this in excel

the sheet looks like this

col1 col2 col3 col4 col5
abc a1 abc 123 a1
xyz z1 abc 345 a1
xyz 789 z1

The output that I want is
col1 col2 col3 col4 col5
abc a1 abc 123 a1
abc 345 a1
xyz z1 xyz 789 z1

I am matching the col2 and col5 and when they dont match i am placing blank
row.

I'd appreciate help with this
