Answer:

Chiral:

3-Methyl-2-butanol

Achiral:

1-Pentanol

3-Pentanol

3-Methyl-1-butanol

Explanation:

Only the molecule that bears a carbon atom surrounded by 4 different groups can be said to be Chiral, the other molecules don't satisfy this property.

Answer:

C5H12O has <em>eight isomers</em>  

Chiral isomers are:  

Pentan-2-ol

2-Methylbutan-1-ol

3-Methylbutan-2-ol

Achiral isomers are:

Pentan-1-ol

Pentan-3-ol

3-Methylbutan-1-ol

3-Methylbutan-2-ol

2, 2-dimethylpropan-1-ol

Explanation:

C5H12O has eight isomers out of which three are chiral and five are achiral in nature

The isomers that have carbon atom(s) that are surrounded by four different groups are Chiral in nature while those that do not have such carbon atom(s) are achiral.  

Thus, only pentan-2-ol, 2-methylbutan-1-ol and 3-methylbutan-2-ol which have carbon atoms surrounded by four different groups are chiral. The carbon atom carrying the hydroxyl (-OH) group is the chiral carbon atom in these three isomers. While the carbon atoms in the other five isomers are achiral.

A chemist must dilute 61.9 mL of 548. nM aqueous sodium carbonate (Na2CO3) solution until the concentration falls to 484. nM . H
maw [93]

Answer:

The final volume will be "70.08 mL".

Explanation:

The given values are:

Molar mass,

M1 = 548 nM

or,

     = 5.48\times 10^{-7} \ M

M2 = 484 nM

or,

      = 4.84\times 10^{-7} \ M  

Volume,

V1 = 61.9 mL

V1 = ?

By using the expression, we get

⇒ M1\times V1=M2\times V2

or,

⇒            V2=\frac{M1\times V1}{M2}

By substituting the values, we get

                    =\frac{5.48\times 10^{-7}\times 61.9}{4.84\times 10^{-7}}

                    =\frac{339.212}{4.84}

                    =70.08 \ mL

What type of reaction is Pb(NO3)2 (aq) + 2KI (aq) →PbI2 + 2KNO3 (aq)
kifflom [539]

Answer:

Precipitation Reactions

They contain two aqueous reactants, one aqueous product, and one solid product. In this reaction, two soluble products, Pb(NO3)2 and KI, combine to form one soluble product, KNO3, and one insoluble product, PbI2. This is a precipitation reaction, and PbI2 is the precipitate.

Answer:

B. Spring balance - a device used for measuring the weight or force of gravity acting on an object.

Explanation:

A Force is any interaction that changes the motion or position of an obkpjectbthatbit is interacting with. Whenever there is an interaction between two objects, there is a force exerted by each of the objects on one themselves.

Forces are generally divided into contact forces and non-contact over field forces.

In contact forces, the two objects physically in contact with each other. Examples of contact forces are push or pull forces, frictional forces, tensional forces, spring forces, etc.

Non-contact forces are forces in which the two objects interacting do no need to be physically in contact with one another. Examples include, gravitational forces, magnetic forces, electrical forces, etc.

Instruments used in measuring forces are known as force gauges.

From the instruments listed above:

A. A ruler is an instrument used in measuring length

B. Spring balance is a device used for measuring the weight or force of gravity acting on an object.

C. A thermometer is an instrument used in measuring temperature

D. A windbvane is an instrument used in measuring wind direction.

The reaction of pyrrole with bromine forms predominantly __________. View Available Hint(s) The reaction of pyrrole with bromine
xenn [34]

Answer:

a) 2-bromopyrrole

Explanation:

Our options for this questions are:

a) 2-bromopyrrole

b) 2,3-dibromopyrrole

c) N-bromopyrrole

d) 3-bromopyrrole

To understand how the reaction works we have to start with the <u>resonance structures</u>. (Figure 1), on these structures, we will obtain a n<u>egative charge on carbon 2</u> in the pyrrole ring, therefore on this carbon we can generate an attack to an electrophile.

The second step is to check how the mechanism take place. An <u>electrophile is generated</u> by the Br_2 and FeBr_3. This electrophile can be <u>attacked</u> by the negative charge on carbon 2 producing the 2-bromopyrrole. (See figure 2).

I hope it helps!
