Most likely the energy will be released below sun’s photosphere, as its density is very low like 1 to 6000 of air. This would prevent immediate flash visibility. The resulting hot gas will flow up eventually but it will cooler and energy less concentrated. But even if it takes several minutes, it still could produce burns on Earth.
Also something like large Solar flash could happen because of integration of the hot gas from the comet with Sun’s magnetic field, and it hypothetically will result in superflare with strong Solar wind and magnetic effect on Earth.
The temperature during impact will be around 5 mln K on the edge of the comet, as I calculated, which is not enough for any meaningful nuclear reactions. But it doesn’t include any additional heating connected with rising pressure because—and pressure would rise as the comet will compress as it decelerate in the solar medium.
If such reaction will happen it could add more energy to explosion and also produce some radioactive isotopes, which could later become part of Solar find and fallout on Earth. I saw an article long time before about possibility of nuclear reaction during impacts, and I will find it.
I thought more after I posted and concluded that:
