need to know the shape of the C2H5OH molecule?

Answer 1

H3C-CH2-OH. The H3C- is like a three-bladed propeller with the H's hanging out behind at 107deg angles from the C. The -CH2OH is like a three-bladed propeller with two H's and O at 107deg from the C. The H is attached to O and is projecting forward. The front CH2O and the rear H3C- are skewed, so that if you look along the O toward the rear, you will be looking between two H's of H3C-. Likewise if you look along any one of the front H's.
