The strongest bond strength is of HCCH (Ethyne), then comes H₂CCH₂ (Ethene) and H₃CCH₃ (Ethane) has the least bond strength as compare to Ethyne and Ethene.
HCCH > H₂CCH₂ > H₃CCH₃
Strongest ----------------------------------------------> Weakest
Explanation:
Ethyne has triple bond, one sigma bond and two pi bonds, Hence, a greater overlap is found between two carbon atoms which resulted in shortening the bond length (i.e 1.9 Angstrome). Also carbon carbon triple bond has highest force constant value i.e 15 ×10⁵ dyne/cm which is greater than carbon carbon double bond (10 ×10⁵ dyne/cm) and single bond (5 × 10⁵ dyne/cm).
Adenosine triphosphate is the correct answer
Answer: 5
Explanation: Arsenic, As, has 5 electrons in the 4th energy shell. 4s^2 and 4p^3. The electrons being added for the elements scandium through zinc are all going into the 3d orbital, in the 3rd energy shell. They don't count, since valence electrons are only those in the highest energy level, 4 in this case.

Answer:
Distillation
Explanation:
By using the method of distillation we'll identify if there is other properties of liquid by looking the temperatures,the ordor or the boiling point.
