If the difference in electronegativtiy for the atoms in a bond are greater than 0.4,we consider the bond polar, if the electronegativity is less than 0.4, we consider it non polar. if there are no polar bonds, the molecule is non polar.
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
Answer:
Here's what I get
Explanation:
There are two methods of naming esters.
(a) Common names
alkyl alcohol + carboxylic acid ⟶ alkyl carboxylate
To form the name of an ester, you drop the alcohol and -ic acid ending from the names of the reactants.
The name of the ester consists of two words: the name of the alcohol followed by the acid name with the ending -ate.
(b) IUPAC (systematic) names
alkanol + alkanoic acid ⟶ alkyl alkanoate
To form the name of an ester, you drop the -anol and -ic acid endings from the names of the reactants.
The name of the ester consists of two words with the corresponding endings -yl and -ate.
You don't mix the common and IUPAC systems in the same name.
1. ethanol + benzoic acid ⟶ ethyl benzoate
2. benzyl alcohol + acetic acid ⟶ benzyl acetate
3. butanol + butanoic acid ⟶ butyl butanoate (IUPAC)
butyl alcohol + butyric acid ⟶ butyl butyrate (common)
4. pentanol + propanoic acid ⟶ pentyl propanoate (IUPAC)
n-pentyl alcohol + propionic acid ⟶ n-pentyl propionate (common)
5. isopropyl alcohol + formic acid ⟶ isopropyl formate
The claim that the strongest intermolecular interactions between propanol molecules arises from hydrogen bonding is True.
Intermolecular forces are weaker attraction forces that are utilized to define physical characteristics of molecules such as:
- boiling point
- temperature
- density
- melting points
Hydrogen bonding is an type of intermolecular forces.
It is a type of dipole-dipole interaction that only happens when a hydrogen atom is connected to the atomic element of oxygen, nitrogen, or fluorine.
From the question given, in the propanol (CH3CH2CH2OH) molecule, the hydrogen usually has a partially positive charge which attracts the partially negative charge of the oxygen.
Therefore, we can conclude that the claim is True.
