(a)
Interpretation:
The structures of poly (vinyl acetate) and poly (vinyl alcohol) are to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition
(b)
Interpretation:
An explanation to predict that the poly (vinyl acetate) is polyester as vinyl acetate is an ester is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. These polymers are made, when some alkenes undergo chain growth polymerization by some initiator.
(c)
Interpretation:
An explanation corresponding to the given statement that hydrolysis does not destroy the poly (vinyl alcohol) polymer is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. These polymers are made, when some alkenes undergo chain growth polymerization by some initiator.
(d)
Interpretation:
An explanation corresponding to the given statement that the poly (vinyl alcohol) is made by given circuitous route rather than the polymerisation of vinyl alcohol is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. The poly (vinyl acetate) is converted to poly (vinyl alcohol) by a basic hydrolysis of the ester groups.

- Explain the term “inductively coupled plasma.”arrow_forwardUsing Pauling electronegativity values and a Ketelaar triangle, what type of compound is brass, a CuZn alloy? Group of answer choices metallic ionic covalentarrow_forwardChallenging samples: 1. Metal complexes with low volatility are often difficult to analyze when performing atomic absorption measurements because the atomization efficiency is reduced to unacceptably low levels. Devise a strategy or strategies for eliminating the problem of a non-volatile metal complex? Explain how you would do that. 2. Devise a strategy to overcome unwanted ionization of the analyte? Explain what it would be. 3. Devise a general method that can be used to account for the presence of unknown matrix effects.arrow_forward
