Which of the following would have the shortest c-c bond length ch3ch3 chch - ch2ch2 all have the same bond length ch3ch2oh

The molecule having shortest C-C bond is acetylene (CHCH)

Explanation:

Note : CH3CH2OH has longest bond length

The bond length order from longer to shorter is :

CH3CH2OH > CH3CH3 > CH2CH2 > CHCH

(More bond order shorter the bond length)

The C-C bond length in Ethanolis more than ethane

The C-C bond length in Ethane is 1.54 Angstrom

The C-C bond length in Ethene is  1.34 Angstrom

The C-C bond length in acetylene

is 1.20 Angstrom

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
