How do you draw the structure of 5-iodo-2-methoxyhexane?
2 answers:
Answer:
Point out the substituents and longest carbon chain to draw the structure
Explanation:
It is a substituted alkane with longest carbon chain contains 6 carbon atoms ("Hex" denotes 6 carbons and "ane" denotes alkane)
There are two substituents present here- (1) methoxy group at C-2 position and (2) iodo group at C-5 position.
Place these two substituents in main carbon chain to draw 5-iodo-2-methoxyhexane

Explanation:
a) The amount of heat released by coffee will be absorbed by aluminium spoon.
Thus,
To calculate the amount of heat released or absorbed, we use the equation:
Also,
..........(1)
where,
q = heat absorbed or released
= mass of aluminium = 45 g
= mass of coffee = 180 g
= final temperature = ?
= temperature of aluminium =
= temperature of coffee =
= specific heat of aluminium =
= specific heat of coffee=
Putting all the values in equation 1, we get:
80.30 °C is the final temperature.
b) Energy flows from higher temperature to lower temperature.Whenever two bodies with different energies and temperature come in contact. And the resulting temperature of both bodies will less then the body with high temperature and will be more then the body with lower temperature.
So, is our final temperature of both aluminium and coffee that is 80°C less than initial temperature of coffee and more than the initial temperature of the aluminum.
