what is chemical formula of glucose?

  1. C6H12O6

  2. C5H10O11

  3. C12H22O11

  4. C4H8O10


Correct Option: A

AI Explanation

To answer this question, we need to know the chemical formula for glucose. The correct chemical formula for glucose is C6H12O6.

Let's go through each option to understand why it is correct or incorrect:

Option A) C6H12O6 - This option is the correct chemical formula for glucose. It represents 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms, which matches the composition of glucose.

Option B) C5H10O11 - This option is incorrect. It represents 5 carbon atoms, 10 hydrogen atoms, and 11 oxygen atoms, which does not match the composition of glucose.

Option C) C12H22O11 - This option is incorrect. It represents 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms, which does not match the composition of glucose.

Option D) C4H8O10 - This option is incorrect. It represents 4 carbon atoms, 8 hydrogen atoms, and 10 oxygen atoms, which does not match the composition of glucose.

The correct answer is option A. The chemical formula C6H12O6 represents the correct composition of glucose.

what is formula for chloroform?

  1. CHCL5

  2. CH2CL2

  3. CHCL3

  4. CCL4


Correct Option: C

AI Explanation

To determine the correct formula for chloroform, we need to understand the composition and structure of the molecule.

Chloroform is an organic compound that consists of carbon (C), hydrogen (H), and chlorine (Cl) atoms. The molecular formula for chloroform is CHCl3.

From the options provided:

A) CHCl5 - This formula has an extra chlorine atom compared to the correct formula for chloroform.

B) CH2Cl2 - This formula represents dichloromethane, which is a different compound with a different structure.

C) CHCl3 - This is the correct formula for chloroform.

D) CCl4 - This formula represents carbon tetrachloride, which is a different compound with a different structure.

Therefore, the correct answer is C) CHCl3.
