You can see that there is steric and torsional strain once you draw the lewis structure for molecules given. You will notice that the hydrogens in the H2C-CH2 are eclipsed and the carbon atoms are adjacent each other which gives it a torsional strain. When you move up on the molecule you will see that there are two hydrogens that want to occupy the same location which makes this interaction steric. I will post a picture of this to give you a visual in a coupe of minutes once I draw it.
you need to draw Newmann projection througn C2-C3 axis to view it. When two large groups (CH2F and CH2CH3) are eclipsed in the Newmann, you will observe the steric and torsional strain as Martha described.
