Structurally Equivalent Groups-1

For each of the compounds A through F indicate the number of structurally-distinct groups of carbon atoms, and also the number of distinct groups of equivalent hydrogens. Enter a number from 1 to 9 in each answer box.
A three-dimensional model for each compound will be displayed below by clicking on its structure. Remember, many of these compounds are conformationally mobile, and the model depicts only one conformer.

Click a structure (A–F) to view its 3-D model.		A	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
		B	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
		C	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
		D	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
		E	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
		F	Number of distinct carbon atoms: ... Number of distinct hydrogen groups:
