Draw all possible structures for a compound with molecular formula C4H8O that exhibits a broad signal between 3200 and 3600 cm-1
MrRissso [65]

Answer:

Cyclic butanol , 1 cyclopropyl methanol, 1-methyl cyclo propan-1-ol.

Explanation:

IR wave-number of O-H bond = 3600 - 3200 cm^{-1}

The intensity of the signal is broad and strong.

IR wave number of C=C bond = 1680 - 1600 cm^{-1}

The intensity of the signal is weak.But for the given chemical formula it didn't show any signal in its IR spectrum.This means that no unsaturation is present.

IR wave number of C=O bond = 1780 - 1650 cm^{-1}

The intensity of the signal is broad and strong.But for the given chemical formula it didn't show any signal in its IR spectrum. This means that no C=O is present in the compound

For the given formula the possible structures wil be:

C_4H_8O: C_4H_7OH

As we know from the I.R. data that no unsaturation is present which indicates that the given compound has cyclic structure.

The possible structures are attached in an image.

What is the IUPAC name of this compund?​
mr_godi [17]

Answer:

3-ethyl-4-methyl Heptane

Explanation:

longest chain is straight .

we start assigning number from where we are close to the branch to this mean its from left hand side. and we saw two chain 1 is ethyl and other is methyl . In alphabetical order e comes first as compare to m so we write ethyl first after that methyl and than in last we write longest chain name with ane (bcz we only have single vonds).
