Explanation:
ranges from gamma (γ) radiation, which has the shortest wavelength, highest frequency, and greatest energy
Explanation:
nothing halogens dont react with cyclohexane at room tempature they just mix with it
The best option would be C because it looks like a bass and the rest are prehistoric fossils D is a nautilus and A is a dinosaur skull
Answer:
Trend in ionic character of bonds: Cs-F > Si-C > Br-Cl > Cl-Cl
(most) (least)
Explanation:
We know that, percentage ionic character of a bond is proportional to electronegativity difference between two constituting atoms.
Atom Electronegativity
Cs 0.7
F 4.0
Cl 3.0
Br 2.8
Si 1.8
C 2.5
Bond Electronegativity difference
Cs-F 3.3
Cl-Cl 0.0
Br-Cl 0.2
Si-C 0.7
So trend in ionic character of bonds:
Cs-F > Si-C > Br-Cl > Cl-Cl
(most) (least)
