Answer:
The correct option is: b. has a downward projection (on the opposite side from the terminal CH₂OH group).
Explanation:
The Haworth Projection depicts the three-dimensional cyclic structure of the monosaccharides.
The monosaccharide, D-glucose predominantly exists in the pyranose form and is known as D-glucopyranose. The D-glucopyranose has two anomeric forms: α- and the β- form and the carbon-1 (C-1 ) is known as the anomeric carbon.
<u>In the Haworth projection of α-D-glucopyranose</u>, the <u>hydroxyl group of anomeric carbon is projected in the downward direction</u>. Whereas, the <u>terminal CH₂OH group on the carbon-5 (C-5), is projected in the upward direction.</u> Therefore, they are on the <u>opposite sides of the plane of ring</u>.

The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
Answer: Molar mass of thyroxine is 776.5 g/mol.
Explanation:
Mass of thyroxine = 0.455 g
Mass of benzene = 10g =0.01kg (1 kg = 1000 g)
Formula used :
where,
= change in freezing point =
= freezing point constant =
m = molality
Now put all the given values in this formula, we get
Thus molar mass of thyroxine is 776.5 g/mol.
