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

Which statement is true regarding methane and ammonia?
sukhopar [10]
The options for given question are as follow,

1) Methane molecules show hydrogen bonding. 
<span>2) Ammonia molecules show hydrogen bonding. </span>
<span>3) Methane has stronger hydrogen bonding than ammonia. </span>
<span>4) Both the compounds do not show hydrogen bonding. </span>
<span>5) Both the compounds have strong hydrogen bonding.
</span>
Answer:
            Correct answer is Option-2 (Ammonia molecules show hydrogen bonding).

Explanation:
                   Hydrogen bond interactions are formed when a partial positive hydrogen atom attached to most electronegative atom of one molecule interacts with the partial negative most electronegative element of another molecule. So, in Ammonia hydrogen gets partial positive charge as nitrogen is highly electronegative. While the C-H bond in Methane is non-polar and fails to form hydrogen bond interactions.

Can someone balance this chemical equation for me please : )
Gnoma [55]

Answer:

2

Explanation:

Tried out 1, but couldn't get whole numbers on the right side then, so went up to 2, worked

all four numbrrs: 2, 7, 4, 6

The 7 for oxygen got adjusted in the last step of the thinking, because it's the simplest to adjust.

since there are different prime numbers (or rather numbers that don't share prime factors) in the set, the numbers can't be revived by the same number and still give whole numbers as results (they can't be smaller)
