Chemistry
1 answer:
Temka [501]3 years ago
5 0

Answer:

Stretching vibration, and

Bending vibration (Rocking, wagging, Twisting and Scissoring)

Explanation:

  1. Stretching vibration: this causes change in the length of a bond
  2. Bending vibration: this causes change in the angle between two bonds

Bending vibration can occur as rocking, wagging, twisting and Scissoring vibration

2a) Rocking vibration: this causes change in angle between group of the atoms

2b) Wagging vibration: this causes change in angle between the plane of a group of atoms

2c) Twisting vibration: this causes change in the angle between the planes of two groups of atoms.

2d) Scissoring vibration: this causes the movement of two atoms toward and away from each other

What is different about the secondary, tertiary, and quaternary structure of each protein?
sweet-ann [11.9K]
Primary structure is the order in which what amino acid bound the other with a peptide bond. This is coded for by the order of codons in a gene

secondary structure is how the chains on amino acids interact with each other to form beta barrels and alpha helixes. This structure is determined by hydrogen bonds between the different amino acids

Tertiary structure is when the secondary structures interact with each other through disulphide bonds, hydrogen bonds hydrophobic/ hydrophilic interactions etc. This is all determined by the placement of certain anino acids within the proteins secondary structure

Name the following aldehyde:
PIT_PIT [208]

The name of the aldehyde is 4, 7- diethyldecanal (D)

<h3>What are rules for naming organic compounds?</h3>

The rules for naming organic compounds are;

  1. Find the longest carbon chain in the compound. ...
  2. Name the longest carbon chain found
  3. Figure the ending name
  4. Then number the carbon atoms
  5. Name the side groups
  6. Then put the side groups in alphabetical order.

The longest chain of the structure given is 10 (deca)

It is an alkanal due to the presence of the carbonyl -CHO

There are two side groups (ethyl) at the 4th and 7th carbon atoms which are both the same, CH2CH3 and are named diethyl

Thus, the name of the aldehyde is 4, 7- diethyldecanal
