Answer:
Explanation:
In multiplication and division problems, the answer can have no more significant figures than the number with the fewest significant figures.
A calculator gives the result:
163.8 has four significant figures.
8.64 has three significant figures.
You must round to three significant figures.
That is, you drop all the digits to the right of the 9 — the red line in Fig. 1 below. You are rounding to the nearest tenth.
To round a number to the nearest tenth, you look at the digit in the hundredths place (7). See Fig. 2.
If the digit to be dropped is greater than 5 or is 5 followed by at least one non-zero digit, you add 1 to the number in the tenths place (Fig. 3).
Here's how you do it.
- The digit in the hundredths place is 5 followed by non-zero digits.
- Add 1 to the digit in the tenths place (9).
- ⁹/₁₀ + ⅒ = ¹⁰/₁₀ = 1 + ⁰/₁₀ = 1.0
The tenths digit becomes 0 and the ones digit increases from 8 to 9.
The reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a secondary electrophile will decrease.
SN1 exhibits substitution, nucleophilicity, and monomolecular reaction, and is expressed by the expression rate = k [R-LG]. This means that the rate-determining step of the mechanism depends on the degradation of a single molecular species. Multi-step reactions include intermediates and multiple transition states (TS).
The SN1 reaction is a nucleophilic substitution reaction in which the nucleophile replaces the leaving group (similar to SN2). However, the SN1 reaction is a single molecule. The rate of this reaction depends on the concentration of only one reactant.

Methane, CH4, would have the lowest boiling point among the three since it has the lowest number of carbon and has no functional groups. Methanol would have the highest boiling point since it has a functional group which contains hydrogen bonding which much stronger than the one in CH3Cl. Hope this helps.<span />
