Final answer:
To draw the structure for each named compound, identify the carbon chain, place the functional groups at the corresponding positions, and consider the formal charges for functional groups like hydroxylamine. Structures include 5-bromo-3-iodoheptanal and 5-bromo-4-ethyl-2-heptanone.
Step-by-step explanation:
The question pertains to drawing organic chemical structures based on given names, which falls under the domain of organic chemistry. When drawing structures, the carbon chain is identified first, followed by the placement of functional groups and substituents at the correct positions indicated by the locant numbers. For example, a heptanal means a seven-carbon aldehyde, so the aldehyde group (-CHO) will be at the end of the heptane chain, while bromo and iodo indicate the presence of a bromine and iodine atom at the 5th and 3rd position, respectively.
5-bromo-3-iodoheptanal: A linear chain of seven carbon atoms with an aldehyde group at one end, a bromine atom at the 5th carbon, and an iodine atom at the 3rd carbon.
5-bromo-4-ethyl-2-heptanone: A seven-carbon chain with a ketone group (C=O) at the second carbon, a bromine atom at the 5th carbon, and an ethyl group (C2H5) attached to the 4th carbon.
Hydroxylamine (H3NO) Structure
The structure of hydroxylamine would show an NH2 group bonded to an OH group. Oxygen typically has a -2 oxidation state, but in hydroxylamine, it's involved in a single bond with hydrogen and nitrogen, which shifts the formal charges. Calculating formal charges, nitrogen would carry a +1, and oxygen would carry a -1 charge, consistent with the actual structure where one hydrogen is directly bonded to oxygen.
