Question

Convert (CH3)2CH(CH2)2COOCH2CH(CH2CH3)2 to bond like structure (skeleton). Include lone pairs.

Answer 1

The conversion of the molecular formula to a bond-line structure involves identifying the longest carbon chain and appropriately placing all side chains, functional groups, and lone pairs according to the formula given, ensuring each carbon has four bonds.

Step-by-step explanation:

To convert the given molecular formula (CH3)2CH(CH2)2COOCH2CH(CH2CH3)2 to a bond-line (skeleton) structure, we'll follow a step-by-step process. Firstly, the molecular formula implies that the central structure is a carbon chain with side chains and functional groups attached. We need to identify the longest carbon chain which appears to be the one incorporated in the ester functional group (COO).

Here is the step-by-step process:

1. Identify the main carbon backbone which includes a carboxylate ester (COO) functional group.
2. Next, add the branching groups that are indicated by the formula, such as (CH3)2CH-, which represents a carbon atom with two methyl groups (CH3) and an additional hydrogen to fulfill the four bonds of a carbon atom.
3. Include the alkyl side chains (CH2)2 which extends from the main chain.
4. Identify the ester linkage (COO) and add the methylene (CH2) group attached to the oxygen of the ester. Note that the oxygen has two lone pairs which should be included in the structure.
5. At the end of the ester, there is a CH- group bonded to two isopropyl groups (CH(CH3)2). These branches should be represented with lines indicating bonds to the central CH-.
6. Finally, fill in all the hydrogen atoms, keeping in mind that each carbon atom must have four bonds total and all atoms conform to the octet rule.

By following this process, we build up the entire bond-line structure, including necessary lone pairs on oxygens.
