Hybridisation influences the bond length and bond enthalpy strength in organic compounds. The sp hybrid orbital contains more s character and hence it is closer to its nucleus and forms shorter and stronger bonds than the sp3 hybrid orbital.
Melting is equivalent to freezing: a temperature when a solid become a liquid.
Answer:
The correct option is C.
Solutions with low pH values have sour taste.
Explanation:
Low pH value show acidic property which can be define as , -log of conc. of hydrogen ion.
Acid has following properties
- Sour taste
- Turn blue litmus into red
- corrosive
-OH group: Base have OH groups. So it is not correct option so it not correct for low pH i.e. acid
turns litmus paper blue: Base turn red litmus into blue, so it not correct for low pH i.e. acid
feels slippery: Bases are mostly slippery like soap
tastes sour: Sour taste is for acid and bitter taste is for base. So it is correct option for acid
Answer:
A metallic bond.
Explanation:
Potassium is a metal (alkali metal), hence its bonds are metallic bonds.
