Octanoic acid and octanol differ in molecular structure by one oxygen molecule. when smelling these substances, _____.​

Chemistry
1 answer:
Levart [38]3 years ago
8 0

Since the two differ in molecular structure, their recognition profiles for the two substances are very different. Substance identification is a procedure by which the distinctiveness of the substance is recognized. Octanoic acid is the eight-carbon straight chain fatty acid while octanol is a fatty alcohol.

Which electron configuration represents the electrons of an atom in an excited state? * 2-3 2-7-1 2-8 2-8-1​
Lemur [1.5K]

2-7-1

<h3>Further explanation </h3>

Electrons can move the shell up or down by releasing energy or absorbing energy  

Excited electrons show higher electron transfer to the shell by absorbing energy  

So it can be concluded that there are 2 conditions:  

Ground state is the state of electrons filling shell with the lowest energy levels.  

Excited state is the state of electrons which occupies a higher energy level  

The state of excited electrons can be seen from the presence of electrons which do not fill the skin completely but fill the skin afterward  

2-7-1

From its 8 electron configuration, filling 3 shells, 2 electrons in the firs shell, 7 electrons in the second shell and 1 electron in the third shell

the electrons in the third shell should fill the electrons in the second shell first according to Aufbau rule (lower energy shells)

\tt  1s^22s^22p^4\rightarrow ground~state\\\\1s^22s^22p^33s^1\rightarrow excited~state

All factors that cause an increase in the rate of dissolving have what in common?
Nikitich [7]

Answer:

They increase the attractive forces between the solute and solvent particles.

Explanation:

The dissolution of a solute in a solvent depends on interaction between the solute and the solvent. The more the attractive force and interaction between solute and solvent, the greater the greater the rate of dissolution of the solute in the solvent.

The absence of interaction between solute and solvent molecules means that the substance can not dissolve in that particular solvent. Hence, any factor that enhances solute-solvent interaction will enhance dissolution of a solute in a particular solvent.
