#CH_2=CHOH#

The IUPAC name of the compound is ethenol

#"A chain of two carbon" ->"stem name"=> eth#

#"suffix of "C=C->"ene"#

#"suffix of "OH->"ol"#

So complete name

#"eth"+"ene"+"ol"=>ethenol#

'e' the last letter of 'ene' is a vowel which is followed by 'ol' that also begins with another vowel 'o'.So vowel 'e' at the end of suffix "ene" is dropped in the final name.
