Which carboxylic acid can be combined with an alcohol to form the ester shown below?

Chemistry
1 answer:
Anna11 [10]3 years ago
7 0

Answer:

CH₃CH₂CH₂COOH.

Explanation:

To know which option is correct, let us hydrolysed the given ester. This is illustrated in the attached photo.

Hydrolysis of ester involves breaking the ester bond by a water molecule to produce the corresponding alcohol and carboxylic acid.

From the reaction given in the attached photo, we can see that the carboxylic acid needed to produce the desired ester is butanoic acid, CH₃CH₂CH₂COOH.

Frequency = speed of light
                      ---------------------------
                        wavelength 
 
                   =        3 x 10^8
                      ------------------------
                          344 x 10^-9
 
                   =          8.72 x 10^14 Hz.

Hope this helps!

2. What ions are present in what ratio in a solution of aqueous calcium chloride?
Alenkasestr [34]

Answer:

\mathrm{Ca}^{2+} \text { and } \mathrm{Cl} \text { - ions are present in } 1: 2 \text { ratio in a solution of aqueous calcium chloride. }

Explanation:

Here in Calcium Chloride ionic bond is present in between calcium and chlorine atoms. As we know according to Octet rule calcium have two excess atoms and for matching nearest noble gas electronic configuration. It donate two electrons to gain more stability and form \mathrm{Ca}^{2+}, while chlorine is deficient from one electron to meet nearest noble gas electronic configuration therefore two chlorine atoms accept excess electron from calcium individually and form two\mathrm{Cl}^{-} ions.

\text { Equation is as follows: } \mathrm{Ca}^{2+}+2 \mathrm{Cl}^{-} \rightarrow \mathrm{CaCl}_{2}

Hence aqueous solution of calcium chloride breaks the ionic bond pairing in one \mathrm{Ca}^{2+}and two\mathrm{Cl}^{-}ions: \mathrm{CaCl}_{2} \longrightarrow \mathrm{H}_{2} \mathrm{O} \quad \mathrm{Ca}^{2+}(\mathrm{ag})+2 \mathrm{Cl}(\mathrm{ag})

When monovalent cation (X) binds to divalent anion (Y) it will form
Romashka-Z-Leto [24]

When a monovalent cation X binds to a divalent anion Y, a compound with the formula X_2Y would be formed.

A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be X^+

A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be Y^2^-

Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of  X^+ would be required to successfully bind  Y^2^-

   Y^2^- + X^+ + X^+ ----> X_2Y
