How do amino acids molecules differ from fatty acid molecules

1 answer:

5 0

Short Answer is: fatty acids lack Nitrogen atoms.
Amino acids are the building blocks of proteins. They are made up of the elements carbon, hydrogen, oxygen and nitrogen. They have the functional groups carboxyl (COOH) and amine (H2N).
Fatty acids or LIPIDS - [fats from animals, oils from plants] - are the building blocks of triglycerides. They are made of of carbon, hydrogen, oxygen and DO NOT contain nitrogen. They have the functional groups carbonyl (HCO) and carboxyl (COOH).

A compound is found to contain 13.65 % carbon and 86.35 % fluorine by mass. To answer the question, enter the elements in the or

Nimfa-mama [501]

Answer: The molecular formula will be $CF_4$

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C= 13.65 g

Mass of F = 86.35 g

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{13.65g}{12g/mole}=1.138moles$

Moles of F= $\frac{\text{ given mass of F}}{\text{ molar mass of F}}= \frac{86.35g}{19g/mole}=4.545moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{1.138}{1.138}=1$

For F = $\frac{4.545}{1.138}=4$

The ratio of C : F= 1: 4

Hence the empirical formula is $CF_4$

The empirical weight of $CF$ = 1(12)+4(19)= 88g.

The molecular weight = 88.01 g/mole

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight }}{\text{Equivalent weight}}=\frac{88.01}{88}=$

The molecular formula will be= $1\times CF_4=CF_4$

What intermolecular forces are present among molecules in dimethyl ether, CH3OCH3?

crimeas [40]

Answer:

London forces only

Explanation:

Dimethyl ether is a nonpolar organic compound. Remember that for nonpolar organic substances, London forces are the primary intermolecular forces present.

Since dimethyl ether is a nonpolar organic compound, then it has London forces as its major intermolecular force. Intermolecular forces hold molecules of a substance together in a given state of matter.
