what was the empirical formula for polypropene? and why is the alloy used rather then the metal ?

Was it Ch2 and it was harder stronger and has lower temperatures?

yesss
stronger and lighter is correct for sure because it has properties similar to aluminium

I'm talking about the MCQ too. The one in which we were given 4 elements and we had to identify the transition elements. The right answer was option B, both Q and S
