Draw a skeletal formula for the following molecule: CH 3 CH(CH 3 )CH 2 CH 2 OH.

Here in this practice question it says, draw a skeletal formula for the following molecule. So here we have c h 3 connected to c h, remember parenthesis means that's a branch off of the CH, then it connects the CH connects to CH 2, then another CH 2, then an Oh. Alright, so remember a line connects carbons together. So here we have our CH 3 connected to CH, it has a branching group, branches off of it, Then we have it connected to a CH2, a CH2, and then the OH we actually show. This would be the skeletal formula. Now, if we could go back, you could see that those groups are present. So this is a carbon, carbon must make 4 bonds, so there's 3 hydrogens that are not seen. This carbon here is making 3 bonds that we can see, so it has 1 H that's invisible. This is a carbon up here. Again, carbon must make 4 bonds, so it has 3 hydrogens that are invisible. These 2 carbons, each one's making 2 bonds, so they each have 2 hydrogens. So again, our original skeletal formula is this condensed formula here. So this is the way you should approach it when you're convert for converting a condensed formula into a skeletal formula.

Verified step by step guidance

Identify the main carbon chain in the molecular formula CH3CH(CH3)CH2CH2OH. The longest chain has four carbon atoms, which corresponds to butane.

Determine the substituents on the main chain. The formula CH3CH(CH3)CH2CH2OH indicates a methyl group (CH3) attached to the second carbon and a hydroxyl group (OH) attached to the fourth carbon.

Number the carbon atoms in the main chain from the end nearest to the substituent. In this case, start numbering from the end closest to the OH group to give it the lowest possible number.

Draw the skeletal structure: Start with a zigzag line representing the four carbon atoms in the main chain. Add a line branching off the second carbon to represent the methyl group.

Add the hydroxyl group (OH) to the fourth carbon in the chain. Ensure that the structure reflects the correct connectivity and geometry of the molecule.
