Match these items.
1. ethanol and benzoic acid

2. benzyl alcohol and acetic acid
isopropyl formate
ethyl benzoate
3. butyric acid and butanol
4. n-pentanol and propanoic acid
5. isopropyl alcohol and formic acid
benzyl acetate
pentanyl propanoate

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

i did this but i forgot how to do it

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
