three isomers

I found the following compounds satisfying the given conditions:

4-pentenale $HCOCH_2CH_2CHCH_2$

methyl-allyl-ketone $CH_3COCH_2CHCH_2$

ethyl-vinyl-ketone $CH_3CH_2COCHCH_2$

Calculate the total number of open chain isomeric carbonyl compounds of molecular formula C_5H_8OC_5H_8O which can't show geometrical isomerism?
