select the correct answer. which compound is inorganic? a. c₆h₁₂o₆ b. kh₂po₄ c. ch₃cooh d. c₂h₆ e. c₂h₅oh

Answer

Explanation:

Step1: Recall organic - inorganic compound definition

Organic compounds usually contain carbon - hydrogen bonds. Inorganic compounds generally do not have carbon - hydrogen bonds (with some exceptions like carbonates, cyanides etc. but they are still considered inorganic).

Step2: Analyze option A

$C_6H_{12}O_6$ (glucose) has carbon - hydrogen bonds, so it is organic.

Step3: Analyze option B

$KH_2PO_4$ (potassium dihydrogen phosphate) does not have carbon - hydrogen bonds. It is an inorganic compound.

Step4: Analyze option C

$CH_3COOH$ (acetic acid) has carbon - hydrogen bonds, so it is organic.

Step5: Analyze option D

$C_2H_6$ (ethane) has carbon - hydrogen bonds, so it is organic.

Step6: Analyze option E

$C_2H_5OH$ (ethanol) has carbon - hydrogen bonds, so it is organic.

Answer:

B. $KH_2PO_4$
