Question

compound, drawing of molecule, how many bonds does each element make? water: h₂o, h - 1 single o - 2 single methane ch₄, c - 4 single h - 1 single ethane c₂h₆, c - 4 single h - 1 single ammonia nh₃, n - h - oxygen o₂, o - nitrogen n₂, n - carbon dioxide co₂, c - o - glycine c₂h₅no₂ glucose c₆h₁₂o₆

Explanation:

Step1: Analyze ammonia ($NH_3$)

Nitrogen has 5 valence - electrons and needs 3 more to complete its octet. So, it forms 3 single bonds with hydrogen. Hydrogen has 1 valence - electron and forms 1 single bond. So for ammonia: N - 3 single, H - 1 single.

Step2: Analyze oxygen ($O_2$)

Oxygen has 6 valence - electrons. In $O_2$, each oxygen atom needs 2 more electrons to complete its octet. So, the two oxygen atoms form a double bond with each other. O - 1 double.

Step3: Analyze nitrogen ($N_2$)

Nitrogen has 5 valence - electrons. In $N_2$, each nitrogen atom needs 3 more electrons to complete its octet. So, the two nitrogen atoms form a triple bond with each other. N - 1 triple.

Step4: Analyze carbon dioxide ($CO_2$)

Carbon has 4 valence - electrons and oxygen has 6 valence - electrons. In $CO_2$, carbon forms double bonds with each oxygen atom to complete its octet and for oxygen to complete its octet. C - 2 double, O - 1 double.

Step5: Analyze glycine ($C_2H_5NO_2$)

Carbon: Each carbon atom forms 4 single bonds (in the alkyl part and with other atoms). Nitrogen forms 3 single bonds (1 with carbon, 2 with other atoms). Oxygen: One oxygen forms 2 single bonds (e.g., in a hydroxyl - like group), and the other oxygen forms a double bond (in a carbonyl group). Hydrogen forms 1 single bond. So, C - 4 single, N - 3 single, O - 1 double and 1 with 2 single, H - 1 single.

Step6: Analyze glucose ($C_6H_{12}O_6$)

Carbon forms 4 single bonds (in the ring and chain structure). Oxygen: Some oxygen atoms form 2 single bonds (e.g., in hydroxyl groups) and some form a double bond (in a carbonyl group). Hydrogen forms 1 single bond. C - 4 single, O - some with 2 single and some with 1 double, H - 1 single.

Answer:

Compound	How many bonds does each element make?
Oxygen ($O_2$)	O - 1 double
Nitrogen ($N_2$)	N - 1 triple
Carbon Dioxide ($CO_2$)	C - 2 double, O - 1 double
Glycine ($C_2H_5NO_2$)	C - 4 single, N - 3 single, O - 1 double and 1 with 2 single, H - 1 single
Glucose ($C_6H_{12}O_6$)	C - 4 single, O - some with 2 single and some with 1 double, H - 1 single
