The correct IUPAC name for the following molecule is: _________
andrew-mc [135]

Answer:

A.) trans-2,3-dichloro-5-methyl-2-hexene

Explanation:

The proposed question and structure has been attached to this answer.

The<em> cis</em>- and <em>trans</em>- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:

  • the two chloro groups on the main compound are in opposite directions (-<em>trans</em>), and not the same sides (-<em>cis</em>)
  • The bottom extended methyl group is on the 5th carbon as we count from left to right
  • there's a total of 6 carbon atoms with 1 double bond on the second to third carbon.

Hence the name <u>trans-2,3-dichloro-5-methyl-2-hexene</u>

A 4.00 g sample of a metal (specific heat = 0.600 J g-1°C-1 is heated to 75 degrees Celcius and then dropped into 165 g of water
Bond [772]

Answer:

28.16 °C

Explanation:

Considering that:-

Heat gain by water = Heat lost by metal

Thus,  

m_{water}\times C_{water}\times (T_f-T_i)=-m_{metal}\times C_{metal}\times (T_f-T_i)

Where, negative sign signifies heat loss

Or,  

m_{water}\times C_{water}\times (T_f-T_i)=m_{metal}\times C_{metal}\times (T_i-T_f)

For water:

Mass = 165 g

Initial temperature = 28 °C

Specific heat of water = 4.184 J/g°C

For metal:

Mass = 4.00 g

Initial temperature = 75 °C

Specific heat of water = 0.600 J/g°C

So,  

165\times 4.184\times (T_f-28)=4.00\times 0.600\times (75-T_f)

690360\left(T_f-28\right)=2400\left(75-T_f\right)

692760T_f=19510080

T_f = 28.16\ ^0C

<u>Hence, the final temperature is 28.16 °C</u>
