On our intro organ textbook, page 54, at the very top

I don't understand why we need to put an "E" in front of the compound name in this molecule. Is it because the geometric isomer (the bond between the third C and the fourth C could be in the other direction)?

But if we just write But-2-en-1-ol, is it right?

Because there is a double bond you need to identify the geometric isomer, being cis or tans.

Return to “*Constitutional and Geometric Isomers (cis, Z and trans, E)”
