rank these amino acid from most polar to least: His, Phe, Ser, Ile, Asp, Trp

Question

i don't think my answer is correct...

Ser>Asp>His>Phe>Trp>Ile

Answer 1

I think its correct. lle is the least because it has the longest non polar R group, Ser has an OH the strongest polar group, His has NH group but are attached in ring which makes them least polar, Trp has 2 aromatic rings and Phe has 1 aromatic ring.
