Answer:
4.9 x 10²²hockey pucks
Explanation:
Given parameters:
Number of moles of hockey = 0.0814moles
Unknown:
Number of pucks there = ?
Solution:
A mole of a substance is made up of Avogadro's number of particles.
Therefore;
1 mole of hockey pucks will contain 6.02 x 10²³ hockey pucks
0.0814 mole of hockey pucks will contain :
0.0814 x 6.02 x 10²³ = 4.9 x 10²²hockey pucks
<u>Answer:</u>
Carbon (i) : quaternary carbon
Carbon (ii) : secondary carbon
Carbon (iii) : tertiary carbon
Carbon (iv) : secondary carbon
<u>Explanation:</u>
Carbons can be classified into 4 categories:
(1) Primary carbon : These are the atoms where the carbon atom is attached to one other carbon atom.
(2) Secondary carbon : These are the atoms where the carbon atom is attached to two other carbon atoms.
(3) Tertiary carbon : These are the atoms where the carbon atom is attached to three other carbon atoms.
(4) Quaternary carbon : These are the atoms where the carbon atom is attached to four other carbon atoms.
In the given structure:
Carbon (i) is attached to 4 further carbon atoms and hence, it is a quaternary carbon.
Carbon (ii) is attached to 2 further carbon atoms and hence, it is a secondary carbon.
Carbon (iii) is attached to 3 further carbon atoms and hence, it is a tertiary carbon.
Carbon (iv) is attached to 2 further carbon atoms and hence, it is a secondary carbon.
